I might be wrong, but I think only the 650B rim brake version is discontinued.

ok, that's right, I saw it on the 650b email list.

I don't even know what kind of rims I am using. My LBS manager picked them. They're heavy and they haven't broken yet. If they do, I'll build my wheel lighter.

Same as your rear wheel for cosmetics.

The wheelbuilder I spoke with suggested:

Mavic Open Pro
No. Its aerodynamics are horrible. It bends easier than deeper rims on road obstacles, which is a natural consequence of beam stiffness being proportional to the cube of depth - all else equal a 25mm extrusion would have 250% the stiffness of a 18.4mm deep Open pro.

DT Swiss RR 411 (requires use of their alloy pro head nipples).
I wouldn't do anything which requires proprietary parts, or an oddball rim less likely to be still available when you bend/wear it out and want to replace it without changing spokes and relacing your wheel.

Of those three I'd use the Archetype.

What rim would you suggest and why?
I built my current wheelset using Velocity Fusion HALO retro-reflective powder coated rims (originally a PowerTap front and rear, although I added another front built around a SON28 when I was riding too many hours after dark to rely on battery lights)

They've been around forever, so being able to get another for rim replacement without changing spokes is likely
25mm deep so they're durable without barn door aerodynamics
Not unnecessarily heavy
They're brightly illuminated by vehicle headlights

Thanks, Drew.

I like the idea of the reflective surface of the rim.

I decided on the Archetype.
